WILLIAM JAMIESON, OF MCDONALD, PENNSYLVANIA, ASSIGNOR OF ONE-THIRD TOAUGUST VALENTOUR AND ONE-THIRD TO WILLIAM JAMIESON, JR, OF

MCDONALD, PENNSYLVANIA.

LUBRICATOR.

To all whom it may concern:

Be it known that 1, WILLIAM JAMIEsoN, a citizen of the United States ofAmerica, residing at McDonald, in the county of Washington and State ofPennsylvania, have invented certain new and useful Improvements inLubricators, of which the following is a specification, reference beinghad therein to the accompanying drawmg.

This invention relates to lubricators for mining and pit cars, and theinvention has for its object to provide a novel hub for the wheels of apit car, wherein a lubricant reservoir of improved construction isemployed for thoroughly lubricating the wheels of the same. To this end,I have devised a novel hub or sleeve adapted to revolubly support awheel upon the end of an axle mounted in said hub or sleeve, said hub orsleeve constituting a reservoir for a suitable lubricant which duringthe rotation of said wheel, is equally distributed to the bearingsurfaces of said wheel.

My improved lubricator is particularly designed for mining cars, but itis obvious that the principle of my invention is applicable to varioustypes of wheels which need thorough lubrication, in order to insure aneasy and non-Wearing movement of a car or other vehicle.

The detail construction entering into my invention will be hereinaftermore fully described and then specifically pointed out in the appendedclaims, and referring to the drawing forming part of this specification,like numerals of reference designate corresponding parts throughout theseveral views, in which Figure 1 is an elevation of a mining carequipped with my improved lubricator, Fig. 2 is an elevation of a wheelhaving a hub constructed in accordance with my invention, Fig. 3 is avertical sectional view of the same.

In the accompanying drawing, I have illustrated a conventional form ofmining car 1 which is supported by axles 2 and revoluble wheels 3.

My invention resides in providing the ends of the axles 2 with sleeves 4having inner peripheral flanges 5, and interiorly threaded at the endsas shown at 6.

Upon the sleeves 4 the wheels 3 are adapted to revolve, and to retainsaid wheels thereon, I provide the sleeves 4with exterior threads 7 toreceive a collar or ring 8, said collar or ring retaining the revolublewheels 3 upon the sleeves and against the inner flanges 5.

The sleeves 4 form a cylindrical compartment or reservoir 9 for asuitable lubricant, and in order to retain the lubricant within saidreservoir or compartment, I pro- Specification of Letters Patent.

by a threaded plug 12, while the lubricant is discharged to the bearingsurfaces of the hubs or sleeves through opening 14 which is normallyclosed by the inner surface of the hub of the wheel 3 when the wheelsare at rest. I do not care to confine myself to the manner in which thesleeves are secured upon the ends of the axles 2, and it is obvious thatthe sleeves may be of various lengths to increase the capacity of thelubricant reservoir. With this arrangement it will be noted that thewheel 3 may be removed from the sleeve 4 without detaching the sleeve orinterfering with the lubricant chamber 9, care being taken to see thatthe axle 2 and its detached sleeve 4 is positioned to bring thedisterial will not be allowed to flow out and be lost.

In some instances the screw threaded plugs may be dispensed with, and inproviding the sleeves 4, the outer ends of the same may be closed whenforming said sleeves.

Such variations in the size, proportion and minor details ofconstruction as are permissible by the appended claims, may be resortedto without departing from the spirit and scope of the invention.

What I claim and desire to secure by Letters Patent, is:

1. The combination with an axle and a Wheel, of a sleeve carried by saidaxle on which the wheel is mounted for rotation and extending in advanceof the end of the axle and closed at the outer end, whereby a lubricantreservoir is formed within the sleeve in advance of the 'axle, saidsleeve having a flanged inner end and an externally threaded outer endand a lateral lubricant aperture providing communication between saidlubricant reservoir and the hub of the wheel, and a stop collar,engaging the threaded end of the sleeve and retaining the Wheel thereon,and means for supplying lubricant to said reservoir.

2. The combination with an axle and a wheel, of a sleeve carried by saidaxle and on which the wheel is mounted for rotation, said sleeve beingflanged at the inner end and internally threaded at the outer end andexternally threaded near the outer end, and extending in advance of theend of the axle to provide a lubricant reservoir within the sleeve andprovided with a lateral lubricant aperture providing communicationbetween said lubricant reservoir and the hub of the wheel, an internallythreaded stop collar engaging the external threads of the sleeve andbearing against the wheel hub, a threaded plug engaging the internalthreads of the sleeve to form a closure to said reservoir, and athreaded plug extending through said sleeve between said stop collar andthreaded closure plug.

In testimony whereof I aflix my signature in the presonce of twowitnesses.

WILLIAM JAMIESON.
